Data are not transfered to a table view using signal out
we have recently upgraded to SP16 and I'm now facing a problem on my model that worked fine when we were on SP15.
I have a data service returning data to my model. The data are transfered to a signal out element and then displayed into a table view using a signal in element. Now the table view remains empty.
I have checked that the dataservice returns data because if I directly connect my table view with the dataservice the data are displayed. But my requirement is to use signal in/out elements.
This error was not appearing in SP15.
